Hi,
I have downloaded the latest cvs source and tried again.
I am no longer seeing pkg-config problems when I do the ./configure and
everything compiles and installs without obvious errors.
Everything works fine for the display side of things with the picolcd driver.
Unfortunately I can't seem to get lirc to receive anything on UDP using irw.
I "think" that the picolcd is not sending out UDP but I have no idea how to
test that it. Doing a "nc -p 8765 -u -l" when lircd is disabled also shows
nothing and I have set the UDP options up for the picolcd driver in LCDd.conf
as well as lirc.
Any ideas would be welcome!
Thanks, Peter.

This is likely to be the cause of your problems.

This problem is likely to be caused by the change in CVS with regards
